What the 800 V/µs slew rate buys you
The CLC401AJ is a single-channel current-feedback (CFB) op-amp from Comlinear, built for applications where signal edge fidelity matters more than DC precision. Its 800 V/µs slew rate and 100 MHz -3 dB bandwidth mean it can handle fast pulse trains, video signals, or high-frequency analog paths without the slew-rate limiting that voltage-feedback amplifiers impose at similar gain settings. The current-feedback topology also gives you relatively flat bandwidth over a wide gain range — useful when you are closing the loop at gains of 2 or 5 and still need the full 100 MHz. Input offset voltage runs to 6 mV and input bias current is 30 µA — typical for a CFB input stage, but worth noting if your signal chain demands sub-mV DC accuracy. This part is not a precision amplifier; it is a speed-first building block for pulse, RF, and video front-ends.
Hermetic CDIP and military temperature range
The 8-CDIP ceramic package is a hermetic, through-hole package — the kind you specify when the board will see vibration, humidity, or thermal cycling that would crack a plastic SOIC. The through-hole mounting means the part is not a candidate for high-density SMT reflow. Plan for hand-soldering or wave-solder assembly, and budget the board area for the 0.300-inch-wide DIP footprint. The ceramic body also handles higher soldering temperatures than plastic, but the usual MSL precautions apply — the part ships in a tube, so no moisture-sensitive bake is needed unless the tube has been opened and stored in high humidity.
RoHS non-compliance — plan around it
The CLC401AJ is RoHS non-compliant. That means the leads or internal solder joints contain lead (Pb) above the RoHS threshold. If your BOM requires full RoHS compliance for EU or California markets, this part will not pass without an exemption. For military, aerospace, or medical equipment that is exempt from RoHS, or for legacy designs that already use tin-lead solder, the non-compliant status is irrelevant — and often preferred for reliability reasons (tin whisker mitigation).
Sourcing and lifecycle reality
There is no last-time-buy clock ticking, no successor part to qualify.
